5 Claims.

My invention aims to provide improvements in separable snap fastener installations.

In the drawing which illustrates a preferred embodiment of my invention:-

Figure l is a view of a portion of the inner face of an upholstery panel for attachment to a frame structure and shows the manner of attachment of the fastener stud member;

Fig. 2 is a view of the parts shown in Figure 1 as th y appear when the stud is turned as far as possible in use without contracting the locking boss, and shows that the base and aperture cannot become aligned by accident;

Fig. 3 is a section taken on the line 3-3 of Fig. 1, showing the lost motion connecting means;

Fig. 4 is a plan view of theparts showing the manner of assembly, the boss on the base being compressed; and

Fig. 5 is a section taken on the line 5-5 of Fig. 4.

In the particular embodiment of my invention selected for illustration of my invention, I have shown an upholstery panel structure adapted to be secured to a frame means. My invention is particularly, though not exclusively, adapted for securing upholstered panels to the body framework of motor vehicles. The upholstered part preferably comprises a backing I having elongated oval-shaped apertures 2 and covered on one side with a flexible trimming material 3 (Figs. 3 and 5), which may be assembled prior to attachment to the frame without assembling the fasteners thereto. My invention, therefore, is for the type of installation wherein the snap fastener members are attached to the upholstered part at any time prior to assembly of the installation and after the backing and upholstery have been assembled.

The fastener unit to be attached to the upholstered part is in the nature of a stud member having a thin base 4 elongated in one direction and being in the form of an oval. The material of the base 4 is pressed out to provide a boss 5 about the thickness of the backing I, the usual head 6 and long neck 1 extending from the boss 5, as shown in Fig. 2. The entire unit is divided by a slot 8, which extends lengthwise of the base 4 and nearly to the ends thereof to provide resiliency to the head and the boss. The boss 5 is elongated crosswise of the base 4 and is slightly wider than the narrow diameter of the base but may be reduced to the normal narrow diameter of the base by squeezing the yieldable parts of the stud toward each other, as shown in Figs. 4 and 5.

The assembly of the stud with the upholstered 1933, Serial No. 651,292

part is a very simple operation. Assuming that the backing I has been prepared and that one side of the backing is covered by the material '3 so that the apertures 2 are exposed at one side only of the upholstered part, the attachment of afastener made as followsz first, the stud base i is placed in an aperture 2 in alignment therewith, as shown in Fig. 4; then thehead B of the stud is squeezed to contract the boss '5 so that it may enter the aperture 2 and the basemay. pass therethrough; then, by turning the based beneath the backing, the fastener may be released and it will assume a position somewhat like that shown in Figs. 1 and 2.

When the stud is assembled with the upholture in a frame part.

My improved installation is simple in construction and method of assembly and the fasteners and means of attachment are of a single piece construction and cannot become accidentally disengaged from the backing I because of the boss 5.

While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claims.

I claim:

l. A snap fastener installation comprising, in combination, a fastener-carrying structure having an elongated aperture, a covering material applied to said structure part to cover the aperture at one side and a snap fastener member attached to said fastener-carrying structure, said snap fastener member comprising a base part elongated in one direction and engaging said structure at that side adjacent to the covering lateral shifting movement of the fastener member relative to said structure.

2. A snap fastener installation comprising, in combination, a fastener-carrying structure having an aperture elongated in one direction, a covering material applied to said structure to cover the aperture at one side and a snap fastener member attached to said fastener-carrying structure, said snap fastener member comprising a base part elongated in one direction and being of substantially the same area as said aperture to pass therethrough when aligned therewith, said base underlying said apertured part in a relation crosswise to the elongated aperture therein and a yieldable boss extending from said base into said aperture and being elongated crosswise to said base, the longest diameter of said boss being greater than the narrowest diameter of said aperture thereby to prevent accidental turning movement of the fastener to a position in alignment with said aperture while being adapted to be compressed to permit such rotation for removal of the fastener when desired. 9

3. A snapfastener installation comprising, in combination, a fastener-carrying structure having an apertureelongated in one direction, a covering material applied to said structure to cover the aperture at one side, a snap fastener member attached to said fastener-carrying structure, said snap fastener member comprising a base part elongated in one direction and being of substantially the same area as said aperture to pass therethrough when aligned therewith, said base underlying said apertured part in a relation crosswise to the elongated aperture therein, a yieldable boss extending from said base into said aperture and being elongated crosswise to said base, the longest diameter of said boss being greater than the narrowest diameter of said aperture thereby to prevent accidental turning movement of the fastener to a position in alignment with said aperture while being adapted to be compressed to permit such rotation for removal of the fastener when desired, and said boss being smaller in cross-sectional area than the cross-sectional area of said aperture to permit relative shifting of the fastener in a lateral direction.

4. A snap fastener installation comprising, in combination, a fastener-carrying structure having an aperture elongated in one direction, a covering material applied to said structure to cover the aperture at one side and a snap fastener member attached to said fastener-carrying structure, said snap fastener member comprising a base part elongated in one direction and being of substantially the same area as said aperture to pass therethrough when aligned therewith, said base underlying said apertured part in a relation crosswise to the elongated aperture therein and a yieldable boss extending from said base into said aperture and being elongated crosswise to said base, the longest diameter of said boss being greater than the narrowest diameter of said aperture thereby to prevent accidental turning movement of the fastener to a position in alignment with said aperture while being adapted to be compressed to permit such rotation for removal of the fastener when desired, said boss and said base being divided by a slot extending lengthwise of said base and crosswise of said boss to provide the resiliency to said boss whereby its longest diameter may be reduced.

5. A snap fastener installation comprising, in combination, a fastener-carrying structure I having an elongated aperture 2, a covering material 3 applied to said structure to cover the aperture at one side and a snap fastener member attached to said fastener-carrying structure, said snap fastener member comprising a base portion 4 elongated in one direction to pass through the elongated aperture 2, said base underlying said structure I in a relation crosswise to the elongated aperture 2 therein, a boss 5 pressed from said base and extending into the aperture 2, said boss being elongated crosswise of said base and being longer than the short diameter of the aperture 2 to prevent accidential disengagement of the stud from the structure 2 and a stud head 6 and neck 1 extending integrally from said boss for engagement with a suitable frame structure.
